His eye was not dim, nar his natural force abated - Deuteronomy 34:7
This was true of Moses as a man. He had seen plenty of sorrow and toil; but such was the simple power of his faith, in casting his burden on the Lord, that they had not worn him out in premature decay. There had been no undue strain on his energy. All that he wrought on earth was the outcome of the secret abiding of his soul in God. God was his home, his help, his stay. He was nothing: God was all. Therefore his youth was renewed.
But there is a deeper thought than this. Moses stood for the law. It came by him, and was incarnated in his stern, grave aspect. He brought the people to the frontier of the land, but would not bring them over it: and so the Law of God, even when honored and obeyed, cannot bring us into the Land of Promise. We stand on the Pisgah-height of effort, and view it afar in all its fair expanse; but if we have never got further than "Thou shalt do this and live," we can never pass into the blessed life of rest and victory symbolized by Canaan.
But though the law fails, it is through no intrinsic feebleness. It is always holy, just, and good. Though the ages vanish, and heaven and earth pass away, its jots and tittles remain in unimpaired majesty. It must be fulfilled, first by the Son, then by His Spirit in our hearts. Let us ever remember the searching eye of that holy Law detecting evil, and its mighty force avenging wrong. Its eye will never wax dim, nor its natural force abate. Let us, therefore, shelter in Him, who, as our Representative, magnified the law and met its claims, and made it honorable.
